The Barbary Coast is a vintage cocktail that was created by Harry Craddock and was first published in his 1930 book The Savoy Cocktail Book. It's traditionally made with a gin and Scotch whisky base, white chocolate liqueur, and cream, but this variation, credited to William Elliot of New York, modernizes the recipe by adding rose water, aromatic bitters, and nutmeg. Why Craddock named the drink as such is a mystery, with the possibilities being that the name is a nod to either the coast in Northern Africa or the sultry red light district that existed in San Francisco during the 19th and 20th centuries.
